Schedule WhatsApp Channel posts with Cursor
Tell Cursor what to post and when. It drafts the updates, shows you the exact text, channel and time, and schedules them through Kaption once you say yes: one post, a week of up to 14, or the same update to up to 10 channels and communities.

How do I schedule posts to my WhatsApp Channel with Cursor?
Connect WhatsApp to Cursor with Kaption’s MCP server and ask “plan next week’s posts for my Bakery channel, one a day at 9 AM”. Cursor drafts them, lists each text and time, and schedules them after you confirm. Kaption posts each one from WhatsApp on your computer when it is due. It works in the Kaption app for Mac and Windows now, and in Chrome and Edge with the next extension update.
What do I need to do this in Cursor?
Kaption open on your computer (the extension in WhatsApp Web, in Chrome or Edge, or the Kaption desktop app) with Cloud MCP on, a Kaption account (every account starts with 60 days of Business, unlimited; after that, a plan with credits), and Cursor. Setup takes three steps:
- 02
Install the server in Cursor
Click Add to Cursor on the setup page, or add https://mcp.kaptionai.com/mcp as a server named whatsapp in ~/.cursor/mcp.json (every project) or .cursor/mcp.json (one project).
- 03
Sign in and ask the agent
Enter your phone number and the 6-digit code Kaption sends you on WhatsApp. Then ask the agent in Cursor’s chat; there is no API key to paste.
What should I ask Cursor?
Copy a prompt, paste it into Cursor and change the names to your own chats and contacts.
Draft three posts for my Bakery channel about this week’s specials and schedule them for Monday, Wednesday and Friday at 9 AM. Show me everything first.
Plan next week for my channel: one short post a day at 8 AM. List the texts and times before you schedule anything.
Post the same update to my two channels and the Neighbours community: “We’re closed on Monday for the holiday.” Let me confirm first.
Which channel posts are still waiting to go out? Cancel the one for Friday.
Write a channel post about today’s release from the changelog in this repo and schedule it for 5 PM. Show me the text first.
What can Cursor do here, and what can’t it?
It can
- List the channels you own, administer or follow, and read the latest posts of one.
- Post a text update now, or schedule it for a set date and time, in a channel you own or administer.
- Schedule up to 14 posts in one request, or send the same post to up to 10 channels and communities, spaced at least 2 minutes apart.
- Show what is still waiting, cancel a waiting post, create a channel, or change its name and description.
- Work in VS Code, Windsurf, Zed and other editors with remote MCP and OAuth, at the same address. For a local connection, use npx -y @kaptionai/mcp-extension@latest (Node.js 18 or newer).
It can’t
- Post images, videos, polls or other media: channel posts are text only.
- Show views or other channel insights, invite admins, or delete a channel.
- Post without asking. Cursor shows you the exact text, channels and times first, and a scheduled post is not proof it went out.
- Post while your computer is off. Posts go out from WhatsApp on your computer, so keep Kaption open at the scheduled time.
What leaves my computer?
Scheduled posts wait in Kaption on your computer and go out from your WhatsApp there. Cursor sees your channel names, the recent posts it reads and the texts you agree on.
Kaption’s relay at mcp.kaptionai.com checks your sign-in and passes each request to Kaption on your computer, which runs it against your WhatsApp and sends back only the answer; the relay does not keep your chats. What comes back, such as message text, names and numbers, goes to Cursor, which handles it under its own privacy terms. Locked chats are never visible to the assistant, and you can disconnect at any time.
How many credits does my plan include?
Claude and ChatGPT are unlimited in every account’s first 60 days; after that they need a plan: Lifetime local AI 20 actions a week, Pro 250 credits a month, and Business 500 with its 2 numbers plus 250 for each extra number, shared by all its numbers, the plan to pick when an assistant uses WhatsApp every day. Business Agent includes them with fair use. A read uses 1 credit, a send 2 and a summary 3. See plans and prices
Questions
Will Cursor post to my channel without asking?
No. Before any post, schedule or change, Cursor shows you the exact text, the channels and the times, and waits for your yes. Posting also needs “Assistants can send messages” turned on in Kaption, with sending “From this computer”.
Where does this work today?
In the Kaption app for Mac and Windows, version 0.97.0 or newer. In WhatsApp Web with the Chrome or Edge extension, it comes with the next extension update.
How do I know a post went out?
Scheduling is not proof of delivery. Ask Cursor which channel posts are still waiting, missed or failed, or open the channel in WhatsApp to check.
Does it work in VS Code too?
Yes. The Cursor setup page has an Add to VS Code button, and any editor that supports remote MCP servers with OAuth can use the same address.
